Irell & Manella's Andrei Iancu will be taking a multimillion-dollar pay cut if he's confirmed as President Donald Trump's nominee to head the U.S. Patent and Trademark Office.

According to a financial disclosure form made public last week, Iancu was pulling in roughly $4 million a year from his partnership during 2016-17. That places him just above Irell's average profits per partner of about $2.985 million in 2016, as reported by The American Lawyer. Irell is one of the most profitable law firms in the country.

Iancu holds a diversified portfolio of investments, many of which he has pledged to divest within 90 days of confirmation. One stands out as having a direct tie to Iancu's legal work—a stake of $250,000 to $500,000 in Juno Therapeutics. Iancu helped defend Juno from an attack at the Patent Trial and Appeal Board on one of its cancer treatment patents. Iancu also has represented Juno in its suits against Kite Pharma Inc. in district court, though his name is absent from a new complaint filed earlier this month.
